Application aled June 2, 1931. Srial No. 541,622.

This invention relates to visors or glare shields, and has for an object the provislon of a transparent lare shield colored to subdue thev glare o light transmitted there- 75 through, and 'having sections of diierent thickness, so that the user may, by looking through different sections of the shield, vary the glare-subduing effect thereof. Another object isjto provide a graduated glare shield as described, which is adapted to be mounted upon conventional eyeglasses or spectacles, so as to offer the utmost convenience to the user by making it possible for him to receivel the benefit of the glare shield without the necessity of providing mounting means for the glare shield in addition to his ordinary spectacles.

A further object is to provide a glare shield having the above described characteristics, in which the glare reducing element is transparent so that the users vision therethrough is not impaired, the only effect being to reduce the glare of light from sources within the vision of the user. l

A further object ,is to provide a glare shield as described, which is of a very simple and inexpensive construction, and which is adapted to be mounted in operative position with the utmost ease and with a minimum of inconvenience.

The invention possesses other objects and advantageous features, some of which, with those enumerated, will be set forth in the fol-r lowing description of the inventions particular embodiment which is illustrated in the drawing accompanying and forming a part of the specification.

Referring to the drawing: f

Fig. 1 is a front elevation of a pair of conventional spectacles with glare shields embodying the principles of the present invention operatively mounted thereupon.

Fig. 2 is a transverse vertical sectional 45 view taken upon the line 2-2 of Fig. 1, with the direction of view as indicated.

Fig. 3` is an oblique transverse view taken upon the line 3 3 of Fig. 1, with the direc- Fig. 4 is a top plan view of one of the..

glare shields detached from the spectacles.

Referring to the drawing in detail, where-l in like characters of reference denote likeA` parts throughout, I have shown a pairof my improved glare shields 6 operativelyv mounted in superposed relation'to the lensesl `Y 7 of a pair of conventional eyeglasses or spectacles 8. Whereas the shields 6 may be mounted on substantially any t pe of eyeglasses or spectacles, the spectacles 8 are of the horn rim variety, belng provided with rims or bezels 9 joined by a bridge 11 and :sov

provided with bows 12 whereby the specof various sizes and shapes and held in op- `'m as to permit it to be received upon eyeglasses f erative position thereupon, even though an .l

accurate fit between the shields and the eyeglasses is not established.

The transparent material of which the body portion 16 is composed is colored, any of a relatively large number of colors being suitable for this use. For example, violet, amber, green, andl smoke are colors which are especially serviceable in reducing the glare of light transmitted from light sources within the range of vision of the user.

The body portion 16 of each vof the shields 6 has substantially the configuration of thel segment of a circle, being defined by a straight upper edge 17 and an are 18 at the bottom and so arranged that the body por-` tion 16 extends throughout slightly less than a semi-circle. Furthermore, the curved edgel or arc 18 of the body portion 16 is the arc of a circle, the radius of whichis substantially equal to the radius of the lens 7 `and/or rim v or bezel 9 upon which the shield is to be secured, with the result that the arc Aor curvedl lals mogli edge 18 will overlie the peripheral edge of the lens 7 when the shield 6 is mounted in superposed relation thereto.

The bod portion 16'is provided with sections of di erent thickness so as to offer different degrees of light-subduing eiect by Vpermittin the user to direct his vision through t e selected section. In other words,

the body portion 16 is of graduallyincreas- .ing thickness, the thinnest portlon being preferabl adjacent the center of the straight edge 17, rom which point the bodynportion 16 is of gradually increasing thic ess radially outwards of the curved edge 18. Hence, the color which is imparted to the body portion 16 may-be of a rather delicate shade, inasmuch as the user may, by selecting a different section of the body portion 16 through which to direct his vision,l increase the li ht-subduing effect because of the increased t ickness, and hence increased density, of that section of the body portion through which he elects to look.

Means are provided for mounting the body portion 16 in superposed relation to onel of the lenses 7. An aduncate resilient clip 21 composed preferably of the same material as that of which the body portion 16 is composed, extends from the arcuate edge 18, preferably at a osition olset from the midpoint between t e ends of the straight edge 17. This cli 21 is adapted to embrace the peripheral e ge of the lens 7 and/or the rim or bezel 9, depending up on the type of eyeglasses or spectacles upon which the shield is mounted. If the lenses 7 of the eyeglasses' are not provided with a rim or bezel, the in'- herent resilience of the clip 21 will serve to retain the body portion 16 in operative position simply by drawing the arcuate edge 18 thereof into rictional engagement with the outer surface of the lens 7 adjacent its peripheral edge. ,However, if the spectacles are provided with a rim or bezel, the extreme end 22 of the clip 21 is ada ted to snap behind the rim and to engage t e inner edge thereof, as clearly shown upon Fig. 3, thereby increasing the firmness with which the visor 6 is mounted upon the spectacles. The -clip 21 is relatively long, leaving a material space between the bottom of the clip and the rim 9'so that the shield may be slid further onto the lens. This enables adjustment of the horizontal top edge of the shield with respect to the center of the lens 7.

Whereas the arcuate edge 18 lies substantially in a flat plane, the straight edge 17 is bowed outwards from that plane, with the result that the body portion 16 has substantially the configura-tion of a portion of a sphere. This particular configuration facilitates mounting the device in operative position because of the fact that the curved edge of the lens 7 which leads as it is thrust past the straight edge 17 toward the arcuate edge 18,

is lpermitted to'fit' into the moreor less funne -shaped space 23 behind the body portion 16,'and by continued motion downwards toward the arcuate edge 18 to pass between the arcuate edge 18 and the end 22 of the clip 21. Another advanta e of lthis particular configuration lies in t e fact that the surfaces of the body portion 16 are more nearly perpendicular to the line of vision of the user therethrough, regardless of which dportion of the glare shield the vision is assmg through at any particular time. A jacent the arcuate edge 18, the body portion 16 is deflected outwards as indicated at 24, so that instead of having its extreme edge seat against the lens or bezel, the rounded portion 26 seats against the outer face of the lens along a line spaced .from the edge of the lens and from the bezel 1f the eyeglasses are of the type provided with a bezel.

Although the shields 6 may be mounted u on either the upper or lower edges of t e lenses 7, the general configuration of the body portions 16 and the clips 21 permitting installation in either position, I prefer that they be mounted so as to cover the lower portions of the lenses 7, as clearly illustrated upon Figs. 1, 2 and 3. The reason-for this is that I intend the glare shields to be used princlpallyby automobile drivers who desire protection against the glare of the headlights from automobiles headed in the direction opposite'to that in which the drivers car 1s travehng, inasmuch as these lights are usually at a lower elevation than the e es of the l.100 driver, and it is easier to interpose t e shields b etween t-he drivers eyes and the glaring hghts s1mply by raising the head slightly. Inasmuch as the body portions 16 of the sh1eld s6 are transparent, the visors are of the 105 full-vision type, i. e., `no portion thereof interferes with the normal vision of' the wearer to any extent other than reducin or stopping the glare of light emanating from sources within the wearers line of vision. Because of the fact that the visors 6 are mounted upon the wearers ordinary spectacles practlcally no eliort is necessary to move the visors so as to interpose them between the Wearers eyes and any offending light source, and because of the graduated thickness of each of the body portions 16, just the degree 'of glare-subduing eiect may be attained by moving the head only far enough to interpose the proper portion or portion of proper thickness of the body portions 16 before the pupils of the eyes.

It is to be understood that the details of the invention as herein disclosed, are subject to alteration within the spirit or scope of the appended claims.

I claim:

1. visor Vor glare shield for use in conjunction with spectacles, eye glasses and the hke, comprlsing a concavo-convex member formed of transparent material colored to subdue the glare of light transmitted therethrough, said member being shaped in plan to substantiall cover only a portion of a spectacle lens, aving one straight edge and one arcuate edge, there being an aduncate chp on the arcuate edge extending u wardly over the concave side of the member or fastening the device to the silectacle lens, the arcuate edge being outwar y deflected so as not to engage the edge of the lens or the surrounding frame to limit the lposition of the member with respect thereto w ereby the member may be applied to many types of lenses and may have lts position with respect to the centers thereof adjusted.
